Bedrock is the consolidated rock underlying the surface of a terrestrial planet, usually the rock under the Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The top of the bedrock is known as rockhead and identifying the excavations,drilling or the geophysical methods, is an important task in most civil engineering projects. Superficial deposits can be extremely thick, such that the bedrock lies hundreds of meters below the surface. Trees also are able to form inside most rocks. The Granite gneiss was formed a billion years ago, during what is known as the Grenville orogeny, or mountain-building episode, that marked the creation of an ancient super-continent. It is the crystalline basement rock of the Canadian Shield, the most ancient part of the North American continent.
